Metodología para el diseño geométrico sostenible de ejes viales en vías Intercantonales

Abstract

The deficiencies that occur in the geometric design and road environment factors are related to the risk of traffic accidents, so ensuring a safer road environment is a constant challenge for road authorities and engineers. To address this problem, a methodology for the sustainable geometric design of road axes is proposed, with the aim of reducing the occurrence of unforeseen events and improving road safety. The proposed methodology is based on the analysis of various indicators such as the importance of the road, connectivity, the hazard index and road safety. The process begins with a visual inspection that allows obtaining precise data on land use and the characteristics of the adjacent road environment. Subsequently, a vehicle count is carried out to find out the existing traffic flow on the road and calculate the Average Daily Annual Traffic, a fundamental parameter for classifying the road. Finally, the user's perception of geometric design elements is taken into account, such as sight distance, speed, curve radii, road markings, protection barriers, and lane width. This helps ensure that the road design meets the needs and expectations of drivers. The road E584 Pasaje - EL Guabo was evaluated where a final weight of 0.35 was obtained, which indicates that there is an inadequate road service. In short, a methodology is proposed that, through the use of the land, the geometric design and the lateral zones, allows the evaluation of the road service, in addition, the indicators used in each criterion serve as a guideline to highlight the deficiencies and propose improvements in the design. of the road, with the purpose of increasing the safety and confidence of the driver on the road.
